As we reported yesterday, the Environmental Protection Agency has been collecting data that shows people are drinking water laced with high levels of a weed-killer called atrazine.

But the EPA does not publish that data. (We obtained it through a Freedom of Information Act request.)

Since we have it, we’re publishing the raw data set ourselves. Now you’ll be able to search atrazine levels for about 150 community watersheds in ten states from 2003 to 2008.

We have produced a short video on atrazine as well, featuring interviews with the EPA and a former pesticide lobbyist.

We’ve also added a sample consumer confidence report from McClure, Ohio. In June 2008, weekly EPA data showed a spike of atrazine in McClure’s drinking water at 33.83 ppb, more than 10 times the 3.4 ppb reported publicly by local officials. McClure officials knew of the EPA data, but reported the lower level. Click here to view the report.

Finally, as reported in our story, the National Resources Defense Council, an advocacy organization, released a report this afternoon, analyzing a smaller set of the weekly EPA data —from 2003 through 2006. The NRDC says the “EPA relied on a fatally flawed analytical method to conclude that there was no cause for concern.” Take a look at their state-by-state breakdown of the atrazine levels in raw (unfiltered) water and finished (filtered) water.

If you have any questions about these resources, or atrazine in general, drop us a line.
